Reactoonz 2 Bonus Features

To play this slot effectively, you’ve got to know what’s happening on the grid. This intergalactic slot incorporates avalanche reels with cluster pays mechanics and, much like the original, is centred heavily around a bunch of fun and colourful space critters.

It has three main bonus features, all of which sound slightly bonkers if you never played the first Reactoonz edition. But for the most part, you’re mainly charging two meters in the hope of releasing the giant 3×3 three-eyed blob wild called Gargantoon.


Wilds were there to help you win more in the original Reactoonz and they will help you win more in Reactoonz 2! But with four wilds on offer, you’ll have to keep your eyes laser-focused on the grid to track their movement.

They all have different grid-invasion powers, but only three of them – Energoon wild, the three-eyed Gargantoon wild, and Electric wild – substitute for all symbols.

The Uncharged wilds don’t perform substituting duties nor do they form wins, but they can turn into electric wilds on a couple of occasions.


Positioned at the top right corner, the Fluctometer collects the one-eyed symbols appearing randomly on your gird. If these symbols form a win, then the Fluctometer gets a good charge and fills up depending on how many winning symbols have landed.

At the same time, an electric wild is released to fill any space within the winning cluster on the grid. To unlock the full potential and release up to 3 charged wilds, you’ll have to fill the meter to the brim – 11 charges full.


This meter holds two wilds, Energoon and Gargantoon, which look a little bored until they get some charge into their system. To poke them into life, any non-wild symbols will have to be removed from the grid by an electric wild.

The Quantumeter comes preset with 4 levels and holds a total of 135 charges. Therefore, you’ll need to collect a certain amount of charges for each stage. Depending on the level you’re at, you’ll benefit from multipliers and either two 1×1 or one 2×2 size Energoons or the gigantic 3×3 Gargantoon.

If the 3×3 Gargantoon wild triggers a cascade, it starts shrinking in size and gets replaced by two 2×2 Gargantoon wilds. And once the latter triggers a cascade, then it splits further into nine 1×1 Gargantoon wilds.

Wild Pair Explosion

Once all the features are concluded, and you have two electric wilds remaining on the grid, you’ll have one last feature to help you win – the Wild Pair Explosion. This feature has several outcomes. Two neighbouring electric wilds will explode all symbols (except wilds) around them to clear the grid for a fresh cascade. In the case of electric wilds not being in close proximity to each other, all symbols between them and around them will be destroyed.

Reactoonz 2 Jackpot

Though a jackpot has also been left out in this sequel, it’s good to see the developer bumping up the max potential to 5,083x your stake compared to the original’s 4,530x.

RTP and Volatility

The solid RTP rate of 96.20% and high volatility ensures the possibility of reaching the game’s potential.
